Technical Field
[0001] The present disclosure relates to a fluid collecting device for collecting fluid
such as urine in a laboratory and a pathological analysis center of hospital, and
more particularly to a disposable sealed body fluid retention device.
Technical Background
[0002] Urine analysis results can provide information used for predicting diseases of visceral
organs and determining the current health conditions of the tested subjects, and therefore
are generally employed for testing urine samples from numerous patients, subjects
under physical examination, hospitalized subjects and the like in many hospitals and
laboratory centers.
[0003] Typically, the tested subjects are required to collect their urine samples with paper
cups in the rest room, and then place the paper cups on a specified bracket in the
laboratory or transfer the urine samples into specified test tubes. After being collected
in the laboratory and so on, the urine samples are analyzed in another laboratory.
[0004] In most cases, lots of urine samples are necessarily analyzed completely within one
day. However, these opening paper cups disposed side by side occupy a large space
until the completion of the analysis. Further, when being sent to the laboratory,
the urine samples in the paper cups might be somewhat lost due to possible unintentional
fall or tilting of the paper cups, thus causing environment pollution and waste of
the urine samples. Moreover, the urine samples are collected by most tested subjects
in a volume much higher than that as actually required, thus so many urine samples
together smell badly, resulting in comfortability degradation of the working environment,
as well as lowered working efficiency of doctors, nurses and other personnel for the
urine analysis.
[0005] As can be seen from the above, the conventional urine collecting method is defective.
For example, it is difficult for some tested subjects to excrete urine into the paper
cup, thus sometimes excreting urine on the clothes or hands. Or, the outer wall of
the test tube or fluid storage tube is stained by the urine when the urine is being
transferred to the test tube, as a result, the stained test tube or fluid storage
tube containing the urine cannot be directly put into a urine analysis instrument,
instead the urine needs to be transferred again into a clean test tube or fluid storage
tube. Therefore, the above-mentioned urine collecting method is defective in terms
of sanitation.

a bottom plate provided to the bottom of the shielding side wall, and the bottom plate
may be formed in one piece with the shielding side wall, or the bottom plate and the
shielding side wall may be formed separately and then connected. When the bottom plate
is formed in one piece with the shielding side wall, the shielding body has a cylindrical
shape. When the bottom plate and the shielding side wall are formed separately and
then connected, the shielding body may be formed in one piece with the fluid-taking
piece, or the shielding body may be connected to the fluid-taking piece.
[0020] The shielding side wall may further surround the fluid storage tube at an angle larger
than 360°, so that some of the shielding side wall overlaps.
[0021] The shielding body may be assembled by some components. For example, the shielding
body includes a first component and a second component, which may be fixedly connected.
The first component may be formed in one piece with the fluid-taking piece, or may
be fixedly connected with the fluid-taking piece.
[0022] The shielding body may be fixedly connected with the fluid-taking piece by way of
threads, clip snap, rotatable snap, fastening, interference fit, or magnetic adsorption,
or may be formed in one piece with the fluid-taking piece. Alternatively, the shielding
body may be fixedly connected to the fluid storage tube, for example, the fluid storage
tube is directly inserted into the shielding body, or the shielding body is fixed
to the fluid storage tube by way of threads, clip snap, rotatable snap, or magnetic
adsorption. Alternatively, the shielding body may be fixedly connected to the connector
by way of threads, clip snap, rotatable snap, or magnetic adsorption, for example.

[0023] In the case where the shielding body is fixedly connected to the fluid storage tube
or the fluid-taking piece, the shielding body may be made of flexible material.
[0024] The shielding body has a tubular shape, a C shape or a flat shape. In the case where
the shielding body is fixedly connected to the fluid-taking piece or the connector,
a skidproof structure such as skidproof patterns may be provided on the lower part
of the liquid storage tube, to facilitate the separation of the fluid storage tube
from the connector.
[0025] There may be one or more (such as 1, 2, or 3) air exhaust openings of the air exhaust
passages of the fluid-taking piece. In the case of a plurality of the air exhaust
openings, the air exhaust openings may be arranged in different planes. The air exhaust
opening and the liquid outlet may be arranged in the same plane or in different planes.
Alternatively, at least one air exhaust opening is arranged in the same plane as the
liquid outlet. The air exhaust opening may be located at the bottom of the liquid-taking
piece, or the air exhaust opening may be located at the side surface of the air exhaust
passage. Further, the disposable sealed body fluid retention device may further include
a spacer extension located between the air exhaust opening and the liquid outlet.
The spacer extension may be extended downwards from the spacer and formed in one piece
with the spacer, or may be formed separately from the spacer, to prevent liquid leading
to the liquid outlet from entering into the air exhaust opening.
[0026] The fluid storage tube may be a polygonal tube, for example, a pentagonal tube, a
hexagonal tube or an octagonal tube. Alternatively, only the lower part of the fluid
storage tube has a cross section of a polygonal shape. A skidproof structure may be
provided at the lower part of the liquid storage tube. For example, longitudinal ribs,
such as 2, 3, 4, 5, 6, 7 or 8 ribs, are arranged on the outer wall of the lower part
of the fluid storage tube. Alternatively, a plurality of protrusions, coarse surfaces
or skidproof patterns are arranged on the outer wall of the lower part of the fluid
storage tube, which is not limited herein. The skidproof structure is configured for
easy holding of the liquid storage tube being separated from the fluid-taking piece
and for easy applying of forces to separate the fluid-taking piece from the liquid
storage tube.
[0027] Further, a liquid collecting plate, which is used for collecting urine into the fluid
guiding passage and avoiding spurting of the urine to outside of the fluid-taking
piece during the urine collecting process, is fixed to the top of the annular side
wall of the fluid-taking piece. The fluid-taking piece includes a handle for holding
by hand. The liquid collecting plate may be arranged at both sides of the handle of
the fluid-taking piece, or at either side of the handle. Alternatively, the liquid
collecting plate may be omitted. An anti-spurting layer may be disposed on the annular
side wall of the fluid guiding passage or the spacer to effectively absorb the impact
by the urine in the fluid-taking process, thereby eliminating urine spurted to the
outside of the fluid-taking piece. The anti-spurting layer may be made of a material
with a porous surface.
[0028] The body fluid retention device further includes a connector including an axial through
hole, the lower part of the fluid-taking piece is detachably connected to the through
hole of the connector, and the connector is detachably connected to the opening of

to the through hole of the connector by threads, rotatable snap, interference fit,
fastening, or insertion, which is not limited herein. The connector may be detachably
connected to the fluid storage tube by threads, rotatable snap, or insertion, which
is not limited herein.
[0029] The connector is advantageous for simplifying the manufacturing of the fluid-taking
piece. Particularly, the fluid-taking piece has been separated into two portions which
match each other, to facilitate the manufacturing and assembling of the fluid-taking
piece. Meanwhile, the connector is made of elastic material such as silicone, rubber
and TPE (Thermoplastic Elastomer), which is advantageous for sealing and each inserted
connection between the connector and the opening of the fluid storage tube as well
as between the connector and the lower part of the fluid-taking piece.
[0030] Further, the disposal sealed body fluid retention device further includes a plug
part, which is configured to match with the through hole of the connector or the opening
of the fluid storage tube after the fluid-taking piece is removed, to isolate the
fluid storage cavity from the outside.
[0031] In the case where the connector is movably connected to the lower part of the fluid-taking
piece, it is possible to merely remove the fluid-taking piece and maintain the connection
between the connector and the fluid storage tube, and in this case, the plug part
is mounted onto the through hole of the connector. Alternatively, it is possible to
remove the connector along with removing the fluid-taking piece, and in this case,
the plug part is mounted onto the opening of the fluid storage tube. Here, the plug
part may be formed in one piece with the connector.

tube, and a shielding side wall of the shielding body surrounds the fluid storage
tube at an angle equal to or less than 360°.
- 2) aligning the fluid-taking piece with an outlet where fluid leaks, to collect urine;
and
- 3) pouring excessive urine in the fluid-taking piece after the fluid collecting process
is completed, and separating the fluid-taking piece from the fluid storage tube, where
the shielding body is removed along with the fluid-taking piece, and the fluid storage
tube filled with urine is left.
[0033] A plug part may be further employed to match with the opening to isolate the urine
in the fluid storage tube from the outside.
[0034] In the fluid collecting process of the present disclosure, the step of transferring
the urine from the urine accommodating cup to the fluid storage tube or test tube
is avoided, and the cleanness of the fluid storage tube is ensured and the fluid storage
tube containing the urine can be directly used for testing by urine analyzer and test
paper after the urine collecting process is completed, thereby improving working efficiency.

[0065] In the present embodiment, the fluid-taking piece 2 and the shielding body 4 may
be manufactured separately, and subsequently assembled fixedly or in interference
with each other. Alternatively, the fluid-taking piece 2 and the shielding body 4
may be connected to each other by threads, rotatable snap or magnetic adsorption.
The shielding body 4 may be manufactured by elastic material, and the opening of the
shielding body 4 is connected to the outer wall of the fluid storage tube 1 or the

part 30 of the fluid-taking piece. The air exhaust opening 26 and the liquid outlet
25 are located on the same place. External threads 31 are provided at the lower part
30 of the fluid-taking piece, so that the lower part 30 of the fluid-taking piece
may be detachably connected to the through hole 70 by for example the matching between
the external threads 31 on the lower part 30 of the fluid-taking piece and the internal
threads 74 of the through hole 70. Alternatively, the lower part 30 of the fluid-taking
piece and the through hole 70 may be fixedly connected in other ways, for example
interference fit, fastening, threads in combination with thread adhesive, and so on.
Both the air exhaust opening 26 and the liquid outlet 25 are in communication with
the through hole 70.
[0112] A spacer extension 29, which is extended downwards from the spacer 28 and may be
formed in one piece with the fluid-taking piece 2, is arranged between the air exhaust
opening 26 and the liquid outlet 25. The lowest portion of the spacer extension 29
is disposed lower than the lowest portions of the air exhaust opening 26 and the liquid
outlet 25.
[0113] The liquid collecting plate 6 is fixed to the top of the annular side wall 23 of
the fluid-taking piece 2, and is used for collecting urine into the fluid guiding
passage to avoid spurting of the urine onto the fluid-taking piece 2. An anti-spurting
layer may be further disposed on the fluid guiding passage of the fluid-taking piece
2 to suppress the spurting of urine in the fluid-taking process.
[0114] The shielding body 4 has a tubular shape and may be provided with or without a handle
44. The fluid storage tube 1 is inserted into the shielding body 4, that is, the shielding
body 4 is located outside of the fluid storage tube 1. The shielding body 4 may be
fixedly connected with the lower part 30 of the fluid-taking piece by way of threads,
rotatable snap, interference fit, or fastening. The lowest portion of the shielding
body 4 may be disposed no higher than the lowest portion of the fluid storage tube.
[0115] Alternatively, the shielding body 4 may be formed in one piece with the lower part
30 of the fluid-taking piece. When the shielding body 4 has a tubular shape, the lowest
portion of the shielding body 4 may be disposed no lower than the lowest portion of
the fluid storage tube.
[0116] When the shielding body 4 is fixedly connected to the fluid-taking piece 2, after
the urine collecting process is completed, the handle 33 is held by one hand and the
handle 14 is held by the other hand, so that the shielding body 4 is unthreaded and
then the fluid storage tube 1 is unthreaded, and the plug part 5 is mounted at the
opening 11 of the fluid storage tube 1 to isolate the fluid storage cavity 12 of the
fluid storage tube 1 from the outside. When the shielding body 4 is formed in one
piece with the fluid-taking piece 2, the handle 44 of the shielding body 4 may be
omitted. In this case, after the fluid taking process is completed, the handle 33
is held by one hand and the bottom of the fluid storage tube 1 is held by the other
hand to remove the fluid storage tube 1, and the plug part 5 on the fluid storage
tube 1 is mounted at the opening 11 of the fluid storage tube 1 to isolate the fluid
storage cavity 12 of the fluid storage tube 1 from the outside. When the shielding
body 4 is formed in one piece with the fluid-taking piece 2, the fluid-taking piece
2 and the connector 7 are removed together, and the plug part 5 on the fluid storage
tube 1 is mounted at the opening 11 of the fluid storage tube 1 to isolate the fluid
storage cavity 12 of the fluid storage tube 1 from the outside.
[0117] The connector 7 may be detachably connected with the opening 11 of the fluid storage
tube 1 by way of threads, rotatable snap, insertion and so on. Likewise, the lower
part 30 of the fluid-taking piece may be detachably connected with the connector 7
by way of threads, rotatable snap, clip snap, magnetic adsorption, fastening, interference
fit and so on. In an alternative configuration, not forming part of the claimed invention,
the lower part 30 of the fluid-taking piece may be formed in one piece with the connector
7.

A plurality of protrusions 17 are arranged on the outer wall of the lower part 13
of the fluid storage tube 1.
[0133] The lower part 13 of the fluid storage tube 1 may have a cross section of a polygonal
shape, for example, a pentagonal, hexagonal or octagonal shape. Alternatively, the
fluid storage tube 1 may have a cross section of a polygonal shape, for example, a
hexagonal or octagonal shape.
[0134] The provision of the skidproof structure, such as the ribs, protrusions, skidproof
patterns and coarse surfaces, on the lower part 30 of the liquid storage tube is advantageous
for easy holding of the liquid storage tube 1 being separated from the fluid-taking
piece 2 after the fluid taking process has completed and for easy applying of forces
to separate the fluid-taking piece 2 from the liquid storage tube 1.
[0135] The plug part 5 may employ the structure described below in the present embodiment.
[0136] As shown in Figures 2 and 14, the lower part 13 of the liquid storage tube 1 is inserted
into the plug part 5.
[0137] As shown in Figures 4, 5, 11 and 13, the plug part 5 is connected to the outer wall
of the liquid storage tube 1 and is formed in one piece with the liquid storage tube
1.
[0138] The fluid-taking piece 2 may employ the structure described below in the present
embodiment.
[0139] As shown in Figures 1, the fluid-taking piece 2 includes a fluid guiding passage
21, an air exhaust passage 22, a spacer 28, an annular side wall 23 and a handle 33.
The fluid guiding passage 21 and the air exhaust passage 22 are separated from each
other by the spacer 28 within the annular side wall 23. The fluid guiding passage
21 has one end as a liquid inlet 24 and the other end as a liquid outlet 25, the air
exhaust passage 22 has one end as an air outlet 27 and the other end as an air exhaust
opening 26, and the air exhaust opening 26 and the liquid outlet 25 are at different
planes and preferably the air exhaust opening 26 is at a higher level than the liquid
outlet 25. A holding portion 331 of the handle 33 is disposed higher than the top
of the annular side wall 23. A liquid collecting plate 6, which is used for collecting
urine into the fluid guiding passage to avoid spurting of the urine to outside of
the fluid-taking piece 2, is fixed to the top of the annular side wall 23 of the fluid-taking
piece 2. The liquid collecting plate 6 may be arranged at both sides of the handle
33, or at either side of the handle 33. Alternatively, the liquid collecting plate
6 may be omitted. An anti-spurting layer may be disposed on the fluid guiding passage
21 of the fluid-taking piece 2 to suppress the spurting of urine in the fluid-taking
process. A spacer extension 29, which is extended downwards from the spacer 28, is
arranged between the air exhaust opening 26 and the liquid outlet 25 to prevent liquid
from entering into the air exhaust opening 26. External threads 37 are provided on
the outer wall of the lower part of the fluid-taking piece. A shielding side wall
45 of the shielding body 4 may be formed in one piece with the fluid-taking piece
2, and may have a tubular shape surrounding the fluid storage tube at an angle of
360°. The shielding body 4 is posited at the outside of the fluid storage tube 1,
and the bottom of the fluid storage tube 1 is lower than the lowest portion of the
shielding body 4. As shown in Figure 12, the shielding side wall 45 of the shielding
body 4 is formed in one piece with the lower part 30 of the fluid-taking piece and
has a C-shape (i.e. a sector shape) surrounding the fluid storage tube at an angle
of 340°, and the shielding body 4 is positioned at the outside of the fluid storage
tube 1.
[0140] The connector 7 may employ the structure described below in the present embodiment.
[0141] As shown in Figures 15, the connector 7 includes an axial through hole 70, the wall
of which is provided with internal threads 74. An annular step 71 is provided along
the outer wall of the connector 7 from the lower end face 72 of the connector 7, and
includes a first annular side wall 75, a step surface 77 and a second annular side
wall 76. The first annular side wall 75 is folded in a direction to the center of
the connector 7 to form the step surface 77, the step surface 77 is folded downwards
to form the second annular side wall 76, and the second annular side wall 76 is adjacent
to the lower end face 72. External threads 73 are formed on the second annular side
wall 76. A plug part 15 is disposed on the first annular side wall 75 of the connector
7, and may be formed in one piece with the connector 7.
[0142] As shown in Figures 16, the connector 7 includes an axial through hole 70, the wall
of which is provided with internal threads 74. An annular step 71 is provided along
the outer wall of the connector 7 from the lower end face 72 of the connector 7, and
includes a first annular side wall 75, a step surface 77 and a second annular side
wall 76. The first annular side wall 75 is folded in a direction to the center of
the connector 7 to form the step surface 77, the step surface 77 is folded downwards
to form the second annular side wall 76, and the second annular side wall 76 is adjacent
to the lower end face 72. A plug part 15 is disposed on the first annular side wall
75 of the connector 7, and may be formed in one piece with the connector 7.
[0143] The through hole 70 shown in Figure 15 or 16 may not be provided with internal threads.
[0144] The connector 7 may be made of elastic material such as silicone, rubber and TPU
(Thermo Plastic Urethane), to facilitate the connection and sealing between the opening
11 of the fluid storage tube 1 and the connector 7.
[0145] The liquid collecting plate 6 and the fluid-taking piece 2 may be fixedly connected
in a manner as described below in the present embodiment.
[0146] The liquid collecting plate 6, which is used for collecting urine into the fluid
guiding passage to avoid spurting of the urine to outside of the fluid-taking piece
2, is fixed to the top of the annular side wall 23 of the fluid-taking piece 2. The
liquid collecting plate 6 may be arranged at both sides of the handle 33, or at either
side of the handle 33. Alternatively, the liquid collecting plate 6 may be omitted.
[0147] An anti-spurting layer may be disposed on the fluid guiding passage 21 of the fluid-taking
piece 2 to absorb the impact by the urine in the fluid-taking process, thereby eliminating
urine spurted to the outside of the fluid-taking piece 2.
[0148] In the present embodiment, as shown in Figures 17 to 22, the external threads 73
on the outer wall of the lower part 30 of the fluid-taking piece cooperate with the
internal threads 74 of the through hole 70, and the external threads 73 on the annular
step 71 of the connector 7 cooperate with the internal threads 14 on the inner wall
of the opening 11 of the fluid storage tube 1. In the case where the connector 7 employs
the structure shown in Figure 16, the connector 7 is insertedly connected to the fluid
storage tube, that is, the second annular side wall 76 of the annular step 71 of the
connector 7 tightly cooperates with the inner wall of the opening of the fluid storage
tube 1.
[0149] The lower part 30 of the fluid-taking piece is detachably connected with the through
hole 70, that is, the external threads 31 on the lower part 30 of the fluid-taking
piece cooperate with the internal threads 74 of the through hole 70. Alternatively,
the lower part 30 of the fluid-taking piece may be fixedly connected with the through
hole 70, for example, by the interference fit, fastening, insertion or adhesive (or
by threads or thread adhesive) between the lower part 30 of the fluid-taking piece
and the through hole 70. Both the air exhaust opening 26 and the liquid outlet 25
are in communication with the through hole 70. In the case where the lower part 30
of the fluid-taking piece is insertedly connected with the through hole 70, the wall
of the through hole 70 of the connector 7 may be provided with or without internal
threads.
[0150] To collect the urine, the fluid-taking piece 2 is aligned with an outlet where fluid
such as urine leaks. After a certain amount of the urine has been collected, as shown
in Figures 17 to 20, the handle 33 is held by one hand while the lower part 13 of
the fluid storage tube is held by the other hand, the fluid-taking piece 2 and the
shielding body 4 are removed, and the plug part 5 is placed to match with the through
hole 70 of the connector 7, so that the fluid storage cavity 12 of the fluid storage
tube 1 is isolated from the outside. As shown in Figures 31 and 32, after the fluid
collecting process is completed, the handle 33 is held by one hand while the handle
44 is held by the other hand, and the shielding body 4 is separate from the fluid-taking
piece 2, subsequently the fluid-taking piece is separated from the fluid storage tube,
and finally the plug part is mounted onto the opening of the fluid storage tube.
[0151] In the present embodiment, when the fluid storage tube 1 is formed in one piece with
the plug part 5, the connector may employ the structure as shown in Figure 24, in
which the through hole 70 may be provided with or without internal threads 74. In
the case where the through hole 70 is not provided with internal threads, the lower
part 30 of the fluid-taking piece is insertedly connected with the through hole 70
of the connector 7. The second annular side wall 76 may be provided with or without
external threads 73. In the case where the second annular side wall 76 is not provided
with external threads, the opening 11 of the fluid storage tube 1 is insertedly connected
with the annular step 71 of the connector 7.
Comparative examples
1. Comparison in the perspective of components and structures
[0152] In the present disclosure, there are two components, i.e. the fluid storage tube
and the fluid-taking piece 2 with a shielding body.
[0153] During the urine collecting process, the fluid storage tube and the shielding body
are connected as an integral structure.
[0154] After the urine collecting process is completed, the fluid storage tube is separated
from the fluid-taking piece.
[0155] In the related art, there are two individual components, i.e. a urine accommodating
cup and a fluid storage tube.
[0156] Conclusion: in the related art, operations are complicated, and the fluid storage
tube might be stained by urine when the urine is being transferred to the fluid storage
tube. Therefore, the present disclosure is advantageous in sanitation.
2. Comparison in the perspective of steps of fluid collecting process
[0157] In the present disclosure, there are three steps of collecting urine, removing the
fluid-taking piece from the body fluid retention device, and mounting the plug part.
[0158] In the related art, there are five steps of collecting urine with a urine accommodating
cup, taking a fluid storage tube, pouring the urine into the fluid storage tube, disposing
the urine accommodating cup, and inserting a plug.
[0159] Conclusion: the present disclosure is advantageous for convenience compared with
the related art.
3. Comparison in the perspective of time required for fluid collecting process
[0160] A testing method was conducted and evaluated by average time for fluid collecting
by 50 people.
[0161] The average time is 21 seconds in the present disclosure while the average time is
33 seconds in the related art.
[0162] Conclusion: the time required for fluid taking is reduced to 64% of that in the related
art, so that the convenience and speed is significantly improved compared with the
related art.
4. Comparison in the perspective of spurting of urine during urine collecting process
[0163] In the present disclosure, because a liquid collecting plate and an anti-spurting
layer are disposed on the fluid-taking piece, the spurting of urine is effectively
prevented, meanwhile the urine in the fluid storage tube does not leak during the
process of collecting urine and transferring the urine to the fluid storage tube.
[0164] In the related art, because of the small opening of the fluid storage tube and the
shallow urine accommodating cap, the urine might be spurted onto the fluid storage
tube in transferring the urine from the urine accommodating cup to the fluid storage
tube.
5. Comparison in the perspective of sanitation of fluid storage tube during fluid
collecting process
[0165] In the present disclosure, the fluid storage tube is protected by the annular shielding
body at an angle of 360°, so that the sanitation of the fluid storage tube is fully
ensured during the urine collecting process. Further, after the urine collecting process
is completed, the fluid-taking piece is disposed along with the shielding body which
is formed in one piece with the fluid-taking piece or fixedly connected with the fluid-taking
piece, the cleanness and sanitation of the fluid storage tube is ensured.
[0166] In the related art, because no protection measure is taken in pouring the urine from
the urine accommodating cup to the fluid storage tube, the urine is very likely poured
onto the fluid storage tube, thereby staining the fluid storage tube.
[0167] Conclusion: the inventive device is advantageous in sanitation compared with the
related art.
